Application filed April 2,

My invention 'relates to a new' and useful improvement in car couplings, particularly adapted for use on mine cars, yand has for its object the provision of a couplingvof this class which .will be simple in structure, economical of manufacture and highly cient 'in use. Y A, Another object 'of provision of a` car coupling which may be cheaply manufactured on a mine car, Vand of such durable structure as to the usage to which it is put, while at same time, it will be universally ladaptableV to the various purposes requiredofit in thisuse. "v

Another object of the invention vis the proy vision of a coupling swivelly mounted so as 'to' swing into various positions and .provided with a spring for retracting it .in its housm n l ,n Y

ther objects'will appear hereinafter. The invention consists in the combination and arrangement of parts hereinafter described and claimed.A Y The invention will be best understood by a reference Vto the accompanying drawings which forma partof this specification, Vand in which,f` Y @t if Fig. 1'is a central, vertical, sectional view of the invention vshowing it applied to .a car.

The coupler comprises a link 7 provided with the elongated slot 8 in which engages the securing pin 9 mounted on the forward Aportion 10'ofa car with which used.

spring 11 is attached at one vend to one end of the link 7, and at its opposite endto the bolt 12 which projects through the yfioor 13' of the car and through,4 the Vvtop 14 of a housing. As'shown in Fig. 2, this housing has diverging side walls 15 and 16 which arey cut away as at 17 to permit proper swinging movement of these parts. The. housing shown in Fig. 2 is used on va cooperating link 18 but the housing used inv connection with the link 7 is of the same structure, and therefore a description of one may apply to the other. flhe link 18 s provided With en v eflithe inventionl isy the f withstand the 'in motion,

elongated Vslot through which )extends Aa bolt 20 passing through the floor. 13 of the car and vthrough the top 14 of'lthe housing.

to one end of the linlt The side walls ofthe housing are provided with a-,ilange -21 which is attached to vthe yfloor 13. A spring 22k @0f end yto the bolt 23 extending through the hoor 18 and through the topi 1'4. r Y

They free end of the link 18 4is provided yvvith a pyramidal shaped housing 25, projecting upwardly from which arerlugs y26 and 27, pivotallymounted between which is yan LV-fshaped locking pin28, the-upperend ofiwhich attached to a cord or `chain 29, the other end being secured totheend wall 30df the car. zRockingly mounted by means of clips 31l and 32,0n the endwallBO- of the car Vis a rjod, 33 'having itsend; 34j angularly turned and' provided with the angularly turned portion 315 adapted `tolie behind vthe fastening member 29, -Ihe-st-ructureis such that upon a rocking of the rod 33.,.in its mountin'gs, ythe chain orcord 29` will. be Vengaged and the .member 28 rocked at itspivot,

swinging it inwardly of the housing 25, and'raising itupwardlyfso as to engage in kthe* slot 3,5 formed in the upper wall of they vhousing 2,5, thus AdisengagingV l l from -the` eyelet 36:on the .endof the link 7. v j

-r WhenY it; isjdesired to .engage the eyelet withthe `member 28 the eyeletis inserted into4 the; .htmsingr 25, rocking the member 28 on its pivot so'that the'flree'end thereof will engage in the slot 35. When the end of the eyelet has passed beyond the 'end of the member 28, this member 28 will fall by gravity into the eyelet, thus locking the members together. The links 7 and 18 are swingably mounted as clearly appears from Fig. 4. In addition to being swingably mounted they are longitudinally movable, the engagement'of the bolts20 and 24 in the slots 19 and ment. l'When the carsare used for drawing. each other, thesprings will be placed under tension until the' bolts 24 and 20 engage in theends of the slots sok that a floating movement ofv these connecting'V this -movement permittingl n approach andy withdrawal'of lthe ears while without disturbing the connecting means. In this manner, a ysudden strain exerted uponthe member 28'is eliminated,

soy

8 respectively permitting this movelinks is provided,

the relative 35 I claim as new and and a sudden draw exerted thereon, thus rendering the part whlch is most likely to be broken7 relieved of any sudden strains and jars.

In the use of mine cars it is desirable that the cars be released from the train individually for movement on to the cage. In common practice it is necessary to employ a person for releasing the cars from the train,

10 and in the present invention I have provided a 'device for automatically taking care of this matter.

Mounted adjacent the track 38 is a substantially U shaped member 39 having its bight l5 upwardly inclined at one side7 as` shown in Fig. l, the leg 40 being shorter than the leg 4l. A laterally turned portion l2 of the rod is arranged to engage the bight 39. This U shaped releasing member would be 120 positioned at alocation where it would be desired to release the cars from each other. As the car travels along the track and the laterally turned portion 42 engages the-in. clined bight 39 and rides there along7 the rod 25,33 will be rocked to rock the dog and disengage the oars.

Vhile I have illustrated and described the preferred form of my invention I do not wish to limit myself to the precise details of'structure shown, but desire to avail mypin; a flexible member attached at one end to said couplingpin and at its opposite end to a oar with which used, saidllexible member, upon being drawn taut, effecting a rocking of said coupling pin to inoperative position; and independent means mounted on said end wall and projecting outwardly from each side thereof, engageable with and disconnected from said flexible member for ren-y dering said flexible member taut.

2. In a ear coupling mechanism of the class described, adapted for use with a car having an end wall; a rockably mounted coupling pin; a flexible member attached at one end to said coupling pin and at its opposite end to said end wall, the movement of said flexible member to a tautcondition, effecting a rocking of said coupling pinto inoperative position; and a pair of rockably mounted members on said end wall, each projecting outwardly beyond the edge of said end Wall adjacent opposite ends and each fflisconnected from and engageable with said flexible member for, upon rocking in one direction, movingsaid flexible member to taut condition. s

3. In a car coupling mechanism` of the classdescribed, adapted for use with a car having an end wall: a rockably mounted coupling pin; a flexible member attached at one end to said coupling pin and at its opposite end to said end wall, the movement of said flexible member to a taut condition, effecting a rocking of said coupling pin to inoperative position; a pair of rockably mounted members on said end wall, each projecting outwardly beyond the edge or" said end wall adjacent opposite ends and each disconnected from and engageable with said flexible member for, upon rocking in one direction. moving said flexible member to tautrcondition;

and an inclinedbearing member mounted adjacent the side of the roadbedzfor engaging said rockable members `upon passage of the same thereby and rocking the same.

In vtestimony whereof I 'have signed the foregoing specification'.
